Application led February 19, 1920. Serial No. 359,827.

To all whom t may concern.'

Beit known that I, WILLIAM B. SMITH IVHALEY, a citizen of the United States, and a resident of NewYork city, in the county of New York and State of New York, have invented a new and useful Automatic and Regulable Liquid-Fuel Injection Valve, of which the following is a specification, reference being had to the accompanying sheet of drawing forming part thereof.

This invention relates to liquid fuel injection `valves for internal combustion engines, and has for its object to provide an automatically operated device whichis simple in construction, absolutely reliable in its operations, and may be employed with either two or four cycle engines of anypower or speed, whether operating on gasoline, heavier oilsgor otherforms of liquid fuel.

Another object of the invention is to provide an oil injection device as aforesaid, which receives its impulse from the compression pressure within the cylinder with which the same is associated, and is controlled automatically thereby to yield a corresponding injection of fuel therein to meet the peculiar needs of the engine.

-f-rnotlier object of the invention is to provide a fuel injection valve device which operates automatically in accordance with the compression pressure within the cylinder, and eliminates the need for valve gears usually attending 'oil injection devices.

Still another object of the invention is to provide a device embodying the aforesaid features thereto, which is regulable and controllable, andpossesses a governing feature for the engine. j

To these as well as other ends my invention consists of the novel features of construction, combination, and arrangement of parts described in thefollowi'ng specification and particularly pointed out in the subjoined claims.

rlhe terms employed herein are used in the generic and descriptive sense to designate the elements illustrated, and are therefore not primarily intended as terms of limitation.

ln order to illustrate the invention, have shown in the drawing one embodiment thereof` but without being limited thereto,

Fig. 13 represents a sectional view taken on line 3---3 on Fig. l;

Fig. l represents an enlarged sectional view of the oil regulating` valve mechanism of the device; andy Fig. 5 represents a bottom view of the spray valve or cylinder end of the device.

Like numerals refer to like parts throughout the several views of the drawing.

The numeral l() represents a cylinder of an internal ,combustion engine in which ll is the bore and 12 the compression chamber. 13 represents the header of the cylinder which may be made integral therewith or separate therefrom (as shown in the drawing), and j rigidly secured thereto. Said header i3 is preferably water jacketed, as sliown, and provided with the plunger bore it and the compression duct 15. 16 represents the movable and tubular plunger member which tits within the header plunger bore le with suitable clearance to yield the desired lit therebetween for enabling the plunger member i6 to move up and down therein, as required by the operations of the device. Said plunger member 16 is preferably provided with the internal conical valve seat i7 on the cylinder end thereof, and with the seating flange 18 on the opposite and free end, where said. iiange 18 is cupped to receive the lower end of the timing spring 19 for aligning the same in the device. The plunger member 16 is further preferably provided at the valve or cylinder end thereof with the annular chamber 20 which communicates through the radial and angularly l disposed vent holes 2l with the compression chamber l2 of the engine cylinder. 22 represents a threaded section provided in the pliuiger member which receives the clamping collar 23 and which collar clamps the sealing diaphragm 24 to the seat provided r for in the plunger member, as shown i: said diaphr OIn being preferably yielding slightly to the moveeen said plunger member 16 and the conical er injection valve stem 25 as required in the device. 26 represents the conical injecting valve which is preferably made integral with said valve stern 25, as shown. and provided with the oil plunger bore 27, which telescopingly receives the iXed oil tube 28. 29 represents the oil outlet duct of the valve stem 25 and communicates with the radial spray outlets 30 which are open to the annular oil groove 31 provided in the valve stem 25 above the valve seat 32, as shown. 33 represents the valve stem clamping tube which seals the diaphragm 24 in secured position With the valve stem 25 by means of the nut 34. 35 represents the valve spring (expansion) which is adjusted normally to hold the valve 26 seated With the plunger 14.

36. represents the valve casing which houses the timing spring 19 and provides the seat 37 for the plunger ange 18 and the plunger packing gland 38, as shovvn; said valve casing being preferably open at the top and closed at the bottom, as shown.

40 represents the oil receiving head of the device, which is preferably made of composition or steel, so that the oil will not permeate under high pressure, and is fianged to rit and securely seal the top of'the valve cas ing 36 as by means of the bolts 41. Said oil receiving head 40 is preferably designed With the timing spring guide collar 42, and carries the oil tube 28 fixed thereto, the latter being open tothe oil duct 43 which leads to the vent cock 44 through which air from the chamberl 27 may be drawn off, as may be found necessary.

Communicating with the oil duct 43 is the oil duct 45 which is open to the regulating valve duct 46 through the regulable bypass valve 47 and the delivery oil duct 48 through the ball valve 49 which is held by the expansion spring 50 and is gauged to lift under a pressure exceeding, say 25 pounds per square Vinch for a pressure of, say 25 pounds to the oil-system. 51 represents the oil feed pipe of the device, which connects with the pump 52 through the regulable pump discharge valve as shown.

55 represents the tubular compression duct stud, which threadedly engages at the lovver tend with the header 13, and is threaded at Ythe top to receive the nut 56 whereby said studserves te assist in clamping the oil receiving head 40 and the casing36 together with the head 13. Said stud is preferably provided with the valve seat 57 and thevents 58 and 5 9, said vents opening into thecham ber 60 of the oil header 40 Which is open to the chamber 61 of the casing member 66, as shoivn in 1...

62 represents the compression duct plunger valve, which is ported to allow communication between the compression duct 15 and the vent 58 'which opens into the chamber 60. Said valve 62 is provided with the stem 63 which is guided in the fixed collar 64, Which is secured to the stud 55 and carries secured thereto the spring collar 65 against which the expansion spring 66 acts to normally seat the valve 62. The other end of said spring 66 engages with the adjusting nut 67 through which the valve stem 63 is exposed and squared to allow for the turning of the valve 62 for adj ustmentrand regulating purposes.

68 represents the oil bypass valve plug which isrigidly secured with the oil head 40, as by being securely screwed therein and held by the check nut 69. Said plug 6 8 rotatably holds therein the valve 47 which alsoV protrudes through the plug bonnet 70 for regulating and adjustment purposes. The valve is recessed, vas shown, and carries secured thereto the spring collar 71 againstwhich the expansion spring 72 acts. The bonnet 7 O is adjustable with reference to the plug for adjusting the tension on said bypass spring 72.

Having thus described the parts of the invention in detail, it will be noted that the timing spring should be 'accurately made and adjusted for a pressure to compensate the pressure in the diameter of the valve end of the plunger 16 With the valve 26 seated and so as to permit the plunger to move at the earliest lead desired. The timing spring has a fixed tension and requires no adjustment.

It Will also be noted that the valve spring 35 is adjusted .to normally hold the valve 26 seated against the highest pressure in the oil system, so that said valve 26 cannot be opened normally except through the movement of the plunger 16; j The valve spring 35 may also be provided with a fixed tension, and need not be adjustable.

It will also be noted that the bypass valve 47 is both rotatable and slidable, and is pro vided With a tension spring 72 Which is gaugedY normally to hold the `valve 47 in proximity With the bypass duct 46, as shown in Fig. 1. The rotatable feature thereof permits of regulating the bypass port, which regulates the oil pressure in the plunger bore V27 while the slidable feature thereof allows for the automatic opening of the bypass port when the oil pressure in the plunger bore v27 rises beyond the maximum limit therefor. Should the pressure in the cylinder 11 rise above the safe maximum for which the engine is designed, the pressure would act on the area of the valve 26, causing the valve 26 to close, and consequently the pressure in the plunger bore 27 would rise because of the reduced head'on the atomized oil therein. Such a rise of pressure is at once transmitted tothe bypass valve 47 which forces same away from the oil duet bypass port 46 and results in stopping the delivery of fuel to the engine. To accom* plish the same, the tension on the spring 72- is set about 5 pounds per square inch in excess of the desired pressure on the oil in the oil reservoir orplunger bore 27.

v It will also be noted that the regulating valve 62, which connects the compression space 12 of the cylinder through the duct 15 and vent 58'With the'ivalve casing chamber 61, is designed so that a fixed opening can be made by adjustment to maintain any desired pressure in the spring chamber 61 to increaseor decrease the period or lift to the plunger member' 16, by compensating in part the compression pressure in the cylinder 11 andreducing the period or causing the valve 62 to lift later. The valve 62 is so adjusted. that the tension on its spring 66 holds against any butfthat pressure rise in the cylinder' that would cause rupture therein, when the valve 62 automatically` lifts away i'rom its seat 5i and exposes the chamber 61 to the higher pressure, which would compensate the Whole action oli the plunger 16 and prevent it from delivering fuel to the cylinder until normal pressureis again resumed.-

lt yvill also be noted that the oil system feeding to the device, as suggested, may be 25 pounds, or diiferent, according as may be desired, and that the bypass valve 53 may be coupled `with and automatically regu lated by the governing mechanism or the engine; it being, however, here understood that the valve 53 may be normally set to discharge oil from the pump 52 which lirst reaches a predetermined pressure.

It will also be' noted that the timing spring chamber 61- may be filled with oil, if desired, for cushioning and-lubricating the available working parts of the deif'ice, and that the plunger member 16 may he allowed a substantial lift, as say, normal and 1" maximum for a Vdevice of' the proportion shown in the drawing.

The compression pressure of the engine thus acts onthe plunger 16 and imparts the lifting impulse thereto, carrying with it Jor a period the valve 26 seated and closed. The displacement of the valve liiit, under these circumstances, increases the pressure on the roil in the plunger bore 27 to an entent which forces the valve 26 to become unseated from the plunger seat 17, when the oil from Within the plunger bore 27 is forced out through the setl oi' radial oil vents 30 and is atomized and injected under high pressure into the cylinder. The yield to the diaphragm 24 determines the distance or' opening ot said spray or injecting valve 26. The compression ring 20 acts as a reservoir for compressed air, receiving` same through the decarbonizing ducts 21, vvhrch open to the cylinder just belouT the valve seat (when the valve 26 is seated), and thus ii'rrnishes oxygen onexpansion to consume the surplus arbon or oil at the valve which might otherwise cause trouble by gumrning Vor rcarbonizing. The device is thus automatic in its oilierationsA and regulable,A vcontrolled bythe pressure 'iinpulses occurring ,Within the cylinderT and corinng to load.

automatiially supplied the same with the necessary fuel to meet the various 'working requirements thereof.

The valve inovemenlvv is rilesigned to maintain at all times a head on the atomizcd spray, oil? double the compression pres sure in the cylinder, thus insuring both iinpregnation and turlfuilence in the combustion chamber of the engine.

From the Yforegoing description of parts andjtunctions, it vfll be understood that until con'ipression is attained in the cylinder l1 no fuel will be delivered therein through the device; the delivering or fuel being controlled eni'virely by the demands oi the heat inlto maintain the desired M. E. P. aclli the compression pressure in the cylinder, from any cause, becomes increased or diminished, which would naturally alliect the condition of the media in the cylinder, the valve mechanism of the Within device would automatically adjust itselit1 to cause the condition to resume the normal, which is controlled by the pressure in the pump system, regulated by the gow ernor or the engine, or by the hand regulated bypass el? to control all load and speed requirements.

The pressure in the pump system ranges from, say 25 pounds, under which no oil would be delivered through the springheld ball valve 4:9 up to say 20() pounds per square inch, at which pressure the pressure in the plunger bore 27 would exceed the resisting pres ire by the bypass valve spring 7 2, and instantly open the full bypass; thus relieving all the pressure in the plunger bore 27 required to inject the atomiced oil through the valve 26 and automatically out the fuel 'from the engine. The pressure in the spring chamber 62 is similarly affected by any rise in pressure in the cylinder during` the inJection period, and dampens or stops the action on the plunger member 16, so that here again the supply olg' fuel is automatically reduced or out off. Hence` the range oli pressure in the oil delivering system. 'from say 25 pounds as a minimum, to say 200 pounds as a maximum, gives a range of control for all speeds or variations in loads in the engine, controllable either by aut tically varying the strolre ci the )lunger member 16, plunger on the oil pump .bait goveiuiing` means, loutv` a. vvill be un stood. by hand or governing means applied to open close a bypass troni the supply to the suction oi the pump.

The range oif pressures available through the pressure range in the oil supply systempermits very Wide and ilexible range oi control for all loads., and from no load to lull load. or the reverse au instantaneous control el conditions. The pressure conditions in the cylinder will always oifer the initial means oi rontrol to preserve safety and uniformity of operations, and these are in turn followed up by speed or governing means as a secondary safeguard to Ainsure smooth and imiform regulation.

No injection of fuel can anticipate the necessary compression to ignite it, as until the predetermined, constant working` pressure at which the irilunger 16 begins to act is produced by adiabatic compression, no fuel can be delivered to maintain the pressure by heat influx to the point of cut-off determined by the delivery from the valve, and when adiabatic expansion occurs the valve will close and admit no more fuel to the cycle.

Se that constant pressure at all times is assured, and no excess of fuel can be delivered beyond that necessary te cause this result. There, therefore, can be no after burning or carbonization when the oil bypass is once set for the maximum supply at the full load rating of the engine to properly be consumed by the oxygen furnished by the air means for this full load rating.

The hazard of prematuring is thereby reduced to a minimum or entirely obviated, and the maximum working compression and pressures cannot be exceeded at any time. Therefore, the necessity of anticipating in the design of the engine those abnormal weights caused by having` to design the engines for these abnormal pressure conditions is entirely eliminated. The fuel is at all times, during operations, delivered in the nearest state for perfect combustion and splitting, both by temperature prior to in- `iection and atomization and turbulence at injection to cause perfect combustion.

The fuel is introduced into the cylinder at the most advantageous point, always auto` matically controlled by the valve. Only that amount of fuel to maintain constant pressure is introduced. Complete combustion is assured and is at all times automatically controlled by the device. Combustion takes place at the conical atomizing zone; therefore no carbonizing, sutting or gumming can occur. Atomization is always the same regardless of the oilv used. There are practically no parts subject to shock, fatigue or rupture. All parts are easily accessible, and the life of the device should be no less than the other parts of the engine.
